Exactly that, what is a good book on World War II armour? I kind of need everything on tanks from America, Britain, Germany, Japan, Russia and for good measure, Italy. I kind of need a crash course in World War II vehicles, however I do only need to concern myself with the most widely used or most important types. Before anyone asks, all this research is for a game (Command and Conquer: Generals), if I haven't said it before. While I of course want it to be somewhat accurate, I also want to make it entertaining. Like seeing a T-54 just run over a jeep, not even bothering to fire at it.

Don't get grossed out though, you're in 3
rd person view (looking down at the battlefield), spared of all the details (If you wanted that you'd watch
Saving Private Ryan). Anyway, to give you an idea of what I'm looking for, this is what I have planned for the US (European) so far.
- Aircraft

- Fighter: P-51 Mustang
- Tactical Support: P-47
- Armour
- M4 Sherman as main tank
- M3 Grant/Lee as early tank (mostly because it has two guns)

- Jeep as medical, cargo, support etc.
- Infantry
Keep in mind this list is largely influenced by the one book on tanks I read recently. My main problem, is libraries (at least around here) don't have anything specialized in anything, and what they do have you never know how long you can keep. I'd like to buy a book, but I looking around at sites, I figure most reviews are biased/trying to get you to buy it.
